摘要

摘要: 在肿瘤消融、污水处理等领域的脉冲功率技术应用中，研究发现双极性电脉冲往往比单极性电脉冲效果更佳，这极大地刺激了双极性高压脉冲电源的研发需求。设计了一台基于Boost闭环控制的恒峰值双极性脉冲发生器，该发生器结合boost电路与Marx发生器的特点，实现了具有升压功能的双极性脉冲的产生，且利用峰值检测电路对双极性脉冲发生器的输出峰值进行取样，并反馈到DSP处理器，实现峰值电压闭环控制，从而实现双极性脉冲恒定峰值的输出。为了验证提出的拓扑电路的可行性与稳定性，对5级恒峰值双极性脉冲发生器进行了仿真和实验研究。实验结果表明，当输入电压在100 V时，可产生重复频率5 kHz、脉冲宽度5～10 μs、电压幅值为±2.0 kV的恒峰值双极性脉冲波形。该脉冲电源使用模块化设计，便于级联，结构紧凑，可灵活输出恒峰值的双极性或单极性正（负）脉冲。

Abstract: In the application of pulse power technology in tumor ablation, sewage treatment and other fields, it is found that bipolar electric pulse is often better than unipolar electric pulse, which greatly stimulates the research and development demand of bipolar high-voltage pulse power supply. A constant peak bipolar pulse generator is designed based on Boost closed-loop control. The generator perfectly combines the characteristics of Boost circuit and Marx generator to realize the generation of bipolar pulse with boost function. The peak detection circuit is used to sample the peak value of bipolar pulse and feed it back to DSP to realize closed-loop control, so as to realize the output of constant peak bipolar pulse. To verify the feasibility and stability of the proposed topology circuit, simulation and experiment of the developed 5-stage constant peak bipolar pulse generator are carried out. The experimental results show that when the input voltage is 100 V, a constant peak bipolar pulse waveform with repetition frequency of 5 kHz, pulse width of 5−10 μs and voltage amplitude of ±2.0 kV can be generated. The pulse power supply uses modular design, which is easy to cascade, compact, and can flexibly output bipolar or unipolar positive (negative) pulses with constant peak value.
